I read this manga a while ago but never finished it. I really want to know how it ends but I can't remember the title. All that I can remember is that was about two friends who got drunk (during new years i think?) and one kissed the other. However the one who kissed the main character forgets everything. (i'm pretty sure this actually happens twice, idk it's kinda fuzzy). If anyone knows the name of this I'd really appreciated it!
